Abstract
El presente informe titulado Determinación de la concentración de plomo en tubérculos sembrados en el centro poblado Calipuy, Santiago de Chuco- La Libertad, tuvo como objetivo determinar las concentraciones de plomo en la papa (Solanum tuberosum), cosechadas en los cultivos del centro poblado Calipuy ubicado en Santiago de Chuco, bajo el método de Espectrofotometría de Absorción Atómica con Horno de Grafito. Los puntos de muestreo se tomaron al azar, se eligieron 8 sectores y por cada sector se tomaron 2 puntos. Los resultados que se obtuvieron fueron: En el sector 1 se obtuvo mayor cantidad de plomo siendo el promedio 3.72 mg/L y en el sector 4 se obtuvo la menor cantidad de plomo siendo el promedio 2.32 mg/L de papa. Así mismo informamos que el 100 % de las muestras superaron el límite permisible. Por lo tanto, concluimos que todas las muestras de papa (Solanum tuberosum) recolectadas en centro poblado Calipuy presentan concentraciones de plomo que superan el límite máximo permisible (0.1 ppm) establecido según lo indicado en el CODEX STAN 193-1995, dado por el Codex Alimentarius.
ABSTRACT The present report entitled Determination of the concentration of lead in tubers planted in the Calipuy town center, Santiago de Chuco-La Libertad, had the objective of determining lead concentrations in potatoes (Solanum tuberosum), harvested in the crops of the Calipuy town center. . located in Santiago de Chuco, under the method of Atomic Absorption Spectrophotometry with Graphite Furnace. The sampling points were taken at random, 8 sectors were chosen and 2 points were taken for each sector. The results obtained were: In sector 1, the highest amount of lead was obtained, the average being 3.72 mg/L, and in sector 4, the lowest amount of lead was obtained, the average being 2.32 mg/L of potatoes. We also report that 100% of the samples exceeded the permissible limit. Therefore, we conclude that all potato (Solanum tuberosum) samples collected in the Calipuy town center present lead concentrations that exceed the maximum permissible limit (0.1 ppm) established as indicated in CODEX STAN 193-1995, given by the Codex Alimentarius.
